Application services represent server-based functionality. An application service might be required or optional, and it might require access to a database.
When you run the installer, you can choose to create some services. After you complete the installation, you create other application services based on the license key generated for your organization.
When you plan the application services, you must account for the associated services that connect to the application service. You also must plan the relational databases that are required to create the application service.
